FEED-CUP FOR SEED-DRILLS.

Specification of Letters Patent.

Patented May 26, 1908.

Application filed February 6, 1908. Serial No. 414,606.

To all whom it may concern:

Be it known that I, FRANK DAHLUND, a citizen of the United States,residing at Esmond, in the county of Benson and State of North Dakota,have invented certain new and useful Improvements in Feed-Cups forSeed-Drills; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to improvements in feed cups for seed drills.

The object of the invention is to provide a feed cup of this characterhaving means whereby the same may be readily cleaned out when changingfrom one kind of seed to another, whether the operating mechanism is inor out of gear.

YVith this object in view, the invention 0011- sists of certain novelfeatures of construction, combination and arrangement of parts as willbe more fully described and particu larly pointed out in the appendedclaims.

In the accompanying drawings, Figure 1 is a vertical longitudinalsectional view through a seed cup constructed in accordance with theinvention; Fig. 2 is an edge view; and Fig. 3 is a bottom plan view ofthe same.

Referring more particularly to the drawings, 1 denotes the seed cupwhich may be of any style or design, and is here shown as comprising acasing, 2, provided on its upper end with flanges, 3, by means of whichit is secured to a feed box, or hopper. In the forward edge of thecasing, 2, is formed seeddischarge passage, 4, through which the seed isadapted to be fed into the ordinary drill tubes.

Revolubly mounted in the casing, 2, is a fluted or corrugated feedcylinder, 5, said cylinder being revolved by the usual operating shaftwhich passes therethrough as shown.

In the. lower side 61' edge of the casing is formed a rectangularclean-out opening, 6, over which on the inner side of the casing, isadapted to slide a curved closing plate, 7, said plate being adapted tobe opened or closed and locked in its various positions by means of abolt, 8, which'is secured thereto and projects through a verticallydisposed slot, 9, formed in the curved Tear edge of the casing, asshown. On the bolt, 8, is arranged a clamping washer, 10, and on thethreaded outer end of the bolt is adapted to be screwed a winged nut,12, which, when screwed up on said bolt, will clamp the washer, 10, intoengagement with the outer side of the casing, and thereby draw theclosing plate into tight engagement with the inner side of the casing,thus holding the same in a closed or open position, the plate beingmoved to an open or closed position by moving the bolt, 8, up or down inthe slot, 9.

By providing the clean-out opening 6 in the casing, 2, of the cup, thelatter may be readily cleaned out whether the parts are in or out ofgear, thus providing for the quick changing of the machine for feedingdifferent kinds of seed, the clean-out opening permitting the removal ofseed from the cup and the corrugated surface of the feeding cylinder aswill be readily understood.

Having thus particularly described my in vention, what I claim as new,and desire to secure by Letters-Patent, is:

1. A feed cup for seed drills, comprising a casing having a seeddischarge passage and a clean out passagea plate to cover and uncoversaid clean out passage and means to coact with said casing to hold saidplate in position to cover and uncover said passage, substantially asdescribed.

2. A feed cup for seed drills comprising a casing having formed in itslower edge a clean-out passage, a curved closing plate arranged on .theinner side of said casing and ada ted to be moved back and forth acrosssaid passage to open and close the same, a bolt connected to said plate,and a nut arranged on said bolt to coact with the casing to hold theplate in its adjusted'positions, substantially as described.

3. A feed cup for seed drills comprising a casing having a seeddischarge passage, a'

clean-out passage, and a vertically disposed slot, a segmental coveringplate slidably mounted in the inner side of said casing over saidclean-out passage, a bolt on said plate and projecting through saidslot, a clamping washer on said bolt, and a nut adapted to be screwedinto engagement with said washer to i my hand in presence of twosubsoribing wit clamp the same against the outer side of the nesses.casing and thereby draw said plate into tight engagement with the innerside of the casing, FRANK DAHLUND' 5 thus holding the same in an open orclosed Witnesses:

"position, substantially as described. A. ENGEL,

In testimony whereof I have hereunto set E. O. CRAIG.
